Mark Ogden on what Manchester United must do to defeat Olympiakos and
progress to the quarter-finals

SCORE EARLY:Manchester United must test the nerve of Olympiakos, who will be stuck between sitting on their lead and pushing for a crucial away goal. If Moyes's team can score early, it will boost the atmosphere and heap pressure on the Greek champions to hold out.

PASS THE BALL BETTER: United's woeful passing in Athens contributed to their first-leg downfall, with Michael Carrick and Tom Cleverley over-run by the home team. Deploying Ryan Giggs alongside Carrick would help United control the game better and adhere to the Champions League mantra that possession is king.

STRETCH THE PITCH: Danny Welbeck's goalscoring cameo against West Bromwich Albion 10 days ago highlighted the benefits of utilising his pace up-front. With Welbeck involved, United can stretch the pitch and give Wayne Rooney more space to open up the Olympiakos defence.

DON'T PANIC: United have lost the art of scoring crucial late goals to win games this season, but history has proved the club's ability to leave things very late. The 1999 Champions League triumph over Bayern Munich was achieved with two goals in 'Fergie Time', so there is no need to panic if it is goalless at 60 minutes.
